` DOLLY JACK.. l

To all iff/710m, 'it 77mg/v concern.: f f

Be -it known that we, FELTA B. Gis'r and CHARLES P. BGARTIN, citizens of 'the' United States, residing at Orange, in the county` of Orange and `State of California., have invented new and useful Improvements' in Dolly Jacks, ofwhich the following is a specification.

Our invention relates generally to dollies Lthat are utilized for supporting and towing motor vehicles that can not-be driven by their Vown poweigand more'particularly,v toV an attachment in the nature of a jaclr screw that is adapted to be detachably applied tov .thehody `of the dolly and lwhich attachment may be advantageously used for'engagiiig and lifting Aa part of the motoi'fvehicle and supporting the saine in a solidy and substantialmanner while so' supported and while being towed.y t

-The principal objects of our invention are to provide a simpleand etlicient lifting and carrying device that can be readily applied to or removed from practically vall types'of dollies that are now generally used for supporting and towing motor4 vehicles, tov pro-- vide alifting and carrying attachment for dollies that can beeasilyand quickly manipulated to engage and lift a vehicle so that it may be readily towed, and, further, to provide a lifting and carrying device that will minimize the time andlabor involved in jacking and blocking up a vehicle that is to 'be towed. AWith the foregoing and other objects in view, our invention consists in certain novel Yfeatures of construction and arrangement of parts that will be hereinafter more fully described andxclaii'ned andillustra-ted in theaccompanying. drawings, in which i F ig; lis a top plan view of alifting and carrying device of ourv improved construcf tion.

Fig. 4 -is ai horizontalv section taken approximately on the line 4 4 of Fig. 3.

Fig.y 5 is a sectional view showing an at# tachment that is utilized for yengagingand lifting a vehicle part that rests directly upon the ground.

Referring `by numerals to the accompany.

' ing drawings, which illustrate a' practical f embodiment of our invention, 10 designates thebody of a dolly, the same comprising an elongated vblock of metal, -a'nd extending lengthwise therethrough is a shaftll, o n the endsofwhich are journaled wheels 12.

Formed through thefdolly body 10 andon Yoppositey sidesofI the shaft 1-1, are vertically f disposed `apertures such as 13either one of which Ais adapted to attachment.

receive our improved Two these apertures llfare"pro-vided., in order that,the-lifting and'carrying attachine'nt may be conveniently `positioned when applied to "the f'dollyb'ody for engag? of 'aV vehicle, suchfas andlifting a part therfrontor rear axle.

' Detachably `secured to the front-iside of' lar member 14 that performs the fiinctifonsk ofa tongue when the dolly is used yfor tow# fing a vehicle.

Our improved attachment includes an iny' wardly projecting flange lthat isa'dapted to rest on Atop of the body 10,. Forniedfin this flange 16 is a notch 17'and which latter receives a pin-18 thatis seatedingthe toplof 'the-dolly body 1 0, such construct-ion'holding. Vthe socket member 15 against rotation when appliedto said dolly body.v` f f: i l

Screw seated ln the-'sooket'l is a threaded shaft 19, the upper end of which is provided with an integrally formed headfQO, and re-r movably and rotatably positioned thereupon, isa cap 21 with which is formed integral, a

substantially U-shaped yokeor Vsaddle y22 that is adapted" to receive apart of aiiiotor'` i vehicley'forinstance, the' frontorfrear axle, 'i

ora partof the frame. I

Secured n any v'suitable mannerv tof the upper portion-.ofthe threaded :shaft 1,9, vand preferably at Y a point, immediately; beneath laterally Aproj ectingf arm 25,

ward end of which is adapted to engage b etween the teeth of ratchet wheel 23, and,y in

iodo` vhead 20, is a vratchet wheel 23, and loosely' arranged-on the upper portion of shaft 19 immediately beneath this ratchet wheel,.1s a

discy 24 with which isformed integral, ay

order that said pawl may be utilized for moving the ratchet wheel in both directions, said pawl isconstructed so that its position may be re'x'f'ersed ;Y and to this end, a laterally projecting pin such as 2S is seated in the rear end port-ion of said pawl, and said pin being adapted to engage in either one of a pair of notches such as 29 that are formed in the sides of housing 26 at the rear or outer end thereof. Arm terminates in ai. shank 30, upon which may be detachably positioned the inner end of an eri-tension handla-,31. y

Then it is desired to lift and carry va part ofa vehicle with 'our' improved dolly, the samejis manipulated so that the yoke or saddle 23 is directly beneaththe part to be engaged andx lifted, and handle 31 is now moved back and forth to effect an engagement of the forward end of pawl 27 with the teeth .of the ratchet wheel 33, thereby rotating the same and consequently rotating the threaded shaft 19, upon which said ratchet wheel is mounted.

The threaded shaft 19 operating in socket 15 will be elevated as it is thus rotated, which movement is brought about by the engagement of, the threads of shaft 19 with the threads'in said socket and, as a result, the engaged axle or vehicle part can be elevated to the desired height, and, by making the tongue 14: fast to apart of the vehicle body or to a part of the towing vehicle, the dolly supported vehiclecan be readily towed to thepoint of repair or storage. L To remove the dolly from beneath the ve hicle, it is only necessary to reverse the position of the pawl 27, which is done by engaging pin 2S and withdrawing Said pawl froinengagement with the teeth of ratchet wheel 23, rotating said pawl a half turn, and permittingits point 'to reengage with the teeth ofv said ratchet wh'eel and then rotatshaft 19 b'y manipulation of the handle :n and ai-m 25. l v

. In order to engage and Jlift a motor vehi- Cle part such as an axle while the same is in direct. 'engagement with the ground, we have devised the attachment illustrated in Fig. 5, said attachment comprising a cap 32 that is adapted to lit over head20, and projecting outwardly. and downwardly from the side of said cap', is an arm 33 that terminates in a laterally projecting hook 34. Obviously, when this attachment is applied to the upper end of the screw rod 19, saddle 22 is removed, and, when cap 32 is applied tohead 2O and the screw rod 19 is screwed downwardly through socket 15, the laterally projecting hook 34 can be lowered to a point where it can be readily engaged beneath an axle orv vehicle frame part that is directly upon the ground.

llhere this form of lifting attachment is utilized, we prefer to arrange on the side of the dolly body 10, a roller bearing 35 against which the vertical portion ofthe arm 33 bears while in operation.

A lifting and carrying device of our im* proved construction is comparatively simple, may be easily and cheaply produced, is applicable to the bodies of practically all forms of dollies now in general use, and the use of `said device eliminates much time and labor ordinarily involved in engaging and lifting a vehicle and placing the same in position to be carried by a dolly.

1t will be readily understood thatl minor changes in the size, form and construction of the various parts of our improved lifting and carrying device may be made and substituted for those herein shown and described, witho'ut departing from the spirit of our invention, the scope' of which is set forth in the appended claims. We claim as our invention:

1. In combination, a dolly having an aperture formed therein, a socket member mounted within the aperture, a notched flange formed on one end ofthe socket member, a pin removably mounted in the dolly and engaging the notch of said flange for locking the socket member against rotation within the aperture, a lthreaded shaft mounted 1n the socket member, head formed on the upper end of the shaft,v a wheel having radially extending teeth fixed to' the shaft, any l.

arm ,pivoted on the shaft, a spring pressed pawl carried by the arm and normally engaging said teeth., an operating handle connected to the arm, and means for rotating the pawl to cause the latter to engage the teeth of said wheel to effect. rotation of said shaft in one direction or the other, according as, the arm is moved in one directionoi the other.

2. lnvcombinationya dolly, a jack sup- A ported on the dolly and includinga shaft having a head formed on kthe upper end thereof, a cap sustained on the head, an arm extending downwardly from the cap, and

Xed thereto, a hook vformed on the lower end of the arm, and a roller positioned on the dolly and contacting with said arm.

In testimony whereof we have signedoi'ir names to this specification.
